The Messenger of Allah ﷺ as saying: If anyone buys grain, he must not sell it till receives it in full.  

أَنَّ رَسُولَ اللَّهِ ﷺ قَالَ مَنِ ابْتَاعَ طَعَامًا فَلاَ يَبِعْهُ حَتَّى يَسْتَوْفِيَهُ  

During the time of Messenger of Allah ﷺ we used to buy grain, and he sent a man to us who ordered us to move it from the spot where we had bought it to some other place, before we sold it without weighing or measuring it.  

أَنَّهُ قَالَ كُنَّا فِي زَمَنِ رَسُولِ اللَّهِ ﷺ نَبْتَاعُ الطَّعَامَ فَيَبْعَثُ عَلَيْنَا مَنْ يَأْمُرُنَا بِانْتِقَالِهِ مِنَ الْمَكَانِ الَّذِي ابْتَعْنَاهُ فِيهِ إِلَى مَكَانٍ سِوَاهُ قَبْلَ أَنْ نَبِيعَهُ يَعْنِي جُزَافًا  

They (the people) used to buy grain in the upper part of the market in the same spot without measuring or weighing it. The Messenger of Allah ﷺ forbade them to sell it there before removing it.  

كَانُوا يَتَبَايَعُونَ الطَّعَامَ جُزَافًا بِأَعْلَى السُّوقِ فَنَهَى رَسُولُ اللَّهِ ﷺ أَنْ يَبِيعُوهُ حَتَّى يَنْقُلُوهُ  

The Messenger of Allah ﷺ forbade to sell grain which one buys by measurement until one receives it in full.  

أَنَّ رَسُولَ اللَّهِ ﷺ نَهَى أَنْ يَبِيعَ أَحَدٌ طَعَامًا اشْتَرَاهُ بِكَيْلٍ حَتَّى يَسْتَوْفِيَهُ  

The Messenger of Allah ﷺ as saying: If anyone buys grain, he should not sell it until he measures it. Abu Bakr added in his version: I asked Ibn 'Abbas: Why ? He replied: Do you not see that they sell (grain) for gold, but the grain is still with the seller.  

قَالَ رَسُولُ اللَّهِ ﷺ مَنِ ابْتَاعَ طَعَامًا فَلاَ يَبِعْهُ حَتَّى يَكْتَالَهُ زَادَ أَبُو بَكْرٍ قَالَ قُلْتُ لاِبْنِ عَبَّاسٍ لِمَ قَالَ أَلاَ تَرَى أَنَّهُمْ يَتَبَايَعُونَ بِالذَّهَبِ وَالطَّعَامُ مُرَجًّى  

The Messenger of Allah ﷺ as saying: If anyone buys a grain, he should not sell it until he takes possession of it. Sulaiman b. Harb said: Until he receives it in full. Musaddad added: Ibn 'Abbas said: And I think that everything is like grain.  

قَالَ رَسُولُ اللَّهِ ﷺ إِذَا اشْتَرَى أَحَدُكُمْ طَعَامًا فَلاَ يَبِعْهُ حَتَّى يَقْبِضَهُ قَالَ سُلَيْمَانُ بْنُ حَرْبٍ حَتَّى يَسْتَوْفِيَهُ زَادَ مُسَدَّدٌ قَالَ وَقَالَ ابْنُ عَبَّاسٍ وَأَحْسِبُ أَنَّ كُلَّ شَىْءٍ مِثْلُ الطَّعَامِ  

I saw that during the time of the Messenger of Allah ﷺ the people were beaten when they bought grain on the same spot and sold it there without moving it to their houses.  

رَأَيْتُ النَّاسَ يُضْرَبُونَ عَلَى عَهْدِ رَسُولِ اللَّهِ ﷺ إِذَا اشْتَرَوُا الطَّعَامَ جُزَافًا أَنْ يَبِيعُوهُ حَتَّى يُبْلِغَهُ إِلَى رَحْلِهِ  

I bought olive oil in the market. When I became its owner, a man met me and offered good profit for it. I intended to settle the bargain with him, but a man caught hold of my hand from behind. When I turned I found that he was Zayd ibn Thabit. He said: Do not sell it on the spot where you have bought it until you take it to your house, for the Messenger of Allah ﷺ forbade to sell the goods where they are bought until the tradesmen take them to their houses.  

ابْتَعْتُ زَيْتًا فِي السُّوقِ فَلَمَّا اسْتَوْجَبْتُهُ لِنَفْسِي لَقِيَنِي رَجُلٌ فَأَعْطَانِي بِهِ رِبْحًا حَسَنًا فَأَرَدْتُ أَنْ أَضْرِبَ عَلَى يَدِهِ فَأَخَذَ رَجُلٌ مِنْ خَلْفِي بِذِرَاعِي فَالْتَفَتُّ فَإِذَا زَيْدُ بْنُ ثَابِتٍ فَقَالَ لاَ تَبِعْهُ حَيْثُ ابْتَعْتَهُ حَتَّى تَحُوزَهُ إِلَى رَحْلِكَ فَإِنَّ رَسُولَ اللَّهِ ﷺ نَهَى أَنْ تُبَاعَ السِّلَعُ حَيْثُ تُبْتَاعُ حَتَّى يَحُوزَهَا التُّجَّارُ إِلَى رِحَالِهِمْ
